SARS Audit repeat for unknown reason

Submitted tax return and supporting documents on 25/01/2018. Phoned for feedback and 07/02/2018 and was informed that I was being audited. Why was I not notified?

Received the Completion Letter advising that the audit was finalised on 27/02/2018. Phoned on 28/02/2018 to confirm nothing further was required and was told all is in order and tax refund will be paid within specified time period of 21 days.

Then, on 01/03/2018, I received a new letter asking to re-submit all documents as the audit is to be repeated. Why??? SARS cannot explain why I received the Completion Letter and then 3 days later they want to start the whole audit process again.

They have all documents submitted initially, they have completed the audit, they have confirmed all is in order, and suddenly a few days later they want to restart the whole process again with no explanation whatsoever!!! So, did they lose all documents submitted via e- filing, then make an error auditing it and then sent me the Completion letter in error???!!! The contact centre agent's response was that SARS doesn't make errors and has the right to do whatever they want, so if they want to redo something that they have just confirmed as completed then they can do so.

Great attitude and service: not...

So, what now, they redo the audit a 2nd time, confirm all is in order after their 30 days a 2nd time, then decide to change their minds yet again and want to redo the audit again and again and again????? The complaints in the media is valid. SARS will use any excuse to delay refunding tax monies and their response is simply to say that they can do whatever they want!!! Disgusting!
